About Us

Prüfengel offers authentic consumer tests in which real users share their experiences with products. Our tests are based on practical applications in everyday life and reflect the opinions of consumers. As we focus on consumer tests, we do not carry out any material, long-term or laboratory tests. The tests are carried out by 1-2 independent consumers over a period of 7-14 days. The exact test conditions can be viewed in the test plan of the respective test report – click here to go directly to the test plan.

Manufacturers provide the tested products free of charge. We charge a one-off test fee for carrying out the tests. In addition, manufacturers pay an annual licence fee for the use of the Prüfengel seal. We also receive a commission for linking to manufacturers’ websites. These remunerations have no influence on our test results or ratings.

We guarantee transparency and a fair evaluation. For a detailed insight into our comprehensive evaluation process, please click here.

The grinding wheels were delivered in a sturdy cardboard box that was undamaged and easy to open. The sanding discs were packed in product packaging that protects the product from damage and thus ensures comprehensive product protection. The packaging is made of recyclable materials such as paper and cardboard. Brief instructions on use would be desirable, although the use is self-explanatory for professionals. The product packaging is fully recyclable. The sanding discs make a very good impression at first glance.

Handling the grinding wheels is very easy. They were used with a Rockwell sanding machine. Sanding itself was quick and easy, with impressive results.
The stable material not only ensures a high load-bearing capacity, but also gives the grinding wheels a high level of robustness. This is particularly evident when precision grinding and milling .
The versatility of the sanding discs is reflected in their numerous application options. With smooth running, the sanding discs are perfect for sanding, carving, milling and shaping with all types of wood, but it is important to ensure that the size of the cup wheels is adapted to individual requirements . This is the only way to achieve optimum utilization of the sanding performance . Despite the wide range of functions , the sanding discs are easy to use.
Another outstanding aspect is the durability of the grinding wheels thanks to the high-quality materials. The use of robust carbon steel as the grit material promises long-term use without significant wear.
In summary, it can be said that Adlerfokus grinding wheels are a well thought-out, stable and aesthetic solution for a wide range of applications that meet expectations in terms of quality and functionality .

Price/performance ratio

and ratings from consumers

ℹ️ Finally, we examine how the product compares to the competition. Can it keep up with the competition in terms of price and quality? Would we generally recommend buying it? We also look at the consumer reviews and check whether the critical and positive reviews are actually justified.

On the Amazon platform, consumers rate the product with an average of 4.5 stars. One common complaint is that the sanding discs cannot be tightened on some angle grinders. Many customers like the fact that the quality of the sanding discs is very good. In our practical test, we were able to confirm that the sanding discs are very effective.

Prices of up to €58 are charged on the Internet for equivalent products. Very inexpensive products are available from as little as €14 . The wooden rasp discs from Adlerfokus are therefore currently in the middle price segment with a price of € 29.99 (for 125 mm). For the quality and performance received, the price-performance ratio is very good.
